    Abstract. In this article the authors draw attention to the problem of using the principles of multiculturalism in the organization of architecture-planning environment in European megapolises, in Denmark, Germany, Russia and Holland particularly. Social changes that force architects and designers of urban environment to refer today to the creation of architectural zones, which are intended for integration of refugees and migrants from the Middle East and North Africa countries, are analyzed. The role of architecture in shaping the social space of the city and solving social problems is shown. The authors address the issue of the mission of architecture and design in creating the comfortable multicultural environment of the modern city. The project of the "Superkilen" city park in Copenhagen is analyzed; projects of the location of refugees in the EU countries (in Germany primarily) are considered. The experience in organization of the architectural-planning space in the European Union is compared with the similar experience in the USSR. As an example, the arrangement of the space of the Exhibition of Achievements of National Economy in Moscow is presented. At the end, ways for further research in multicultural urban space are targeted.
    Key words: multicultural architectural environment, multicultural space, architectural-planning environment, integration of migrants and refugees.

    Abstract. At present, the simulation fruitfully develops and is considered as a powerful tool of the theoretical study of non-linear problems in physics, chemistry, biology, material science and other fields. It is used in those situations when it is impossible to set up a full-scale experiment, this is very difficult and very expensive. Analysis of domestic and foreign studies, manuals, and regulatory documents shows that methods of regulating aerodynamic processes through the use of modeling are practically not used on the disturbed territories of cities, which require the development of new modeling solutions in planning projects. The goal of the experimental study of the aeration regime of disturbed areas is to reveal the dependences of values of transformation coefficients on the geometric parameters of an anthropogenic relief. Despite the fact that field observations can give the most correct values of desired coefficients with due regard for all objective factors influencing on them, the preference should be given to experiments in a wind tunnel. They make it possible to vary the geometric parameters of the anthropogenic relief, direction, speed and initial turbulence of the air flow. Experimental studies using the method of physical modeling in the wind tunnel is based on the current theory of aerodynamic similarity. In accordance with this, it is necessary to develop a physical model describing the terms of this aerodynamic process.
    Key words: modeling, wind tunnel, disturbed areas, anthropogenic relief, wind, air flow, theory of similarity, profile of wind speed.

    Abstract. The article presents features of interaction of direct and reflective modes on the example of a pole of concrete mixes of various elasticity and viscosity. The analytical decision is connected with the description of an oscillation process with the use of Kelvin-Voigt model. Solutions for determining elastic and viscosity modules of different movable and rigid concrete mixes have been obtained. There have been compared theoretical and experimental values of the dynamic pressure and acceleration rate for different layers of the concrete mix. It is shown that depending on the ratio of the pole height and wave length there can be different situations called vibration modes which define the resonant phenomena and different dynamic loads on the layers, including seismic loads on constructions.
    Key words: direct and reflected waves, visco-elastic media, concrete mix, elasticity modulus, viscosity modulus, Kelvin-Voigt model.

    Abstract. On the basis of the general theory of mathematical modeling of large systems, the article provides the description and the formal representation of the interaction between the two systems: the foundation and the base (the environment). It discusses the determination of adaptation criteria of the interacting systems, and shows that the adaptation criterion is the major criterion for evaluating the reliability and durability of the system. It also makes it possible to measure the degree of conformity of the two interacting systems, the range of favorable values of intersecting parameters. The interaction system of the foundation and environment has random variables and functions on the intersection. At this, the number of conformity fields equals to the number of parameters at the intersection. The adaptation criterion varies from zero to one. The explanation of the calculation formulas for calculating the adaptation criterion is provided. The adaptation criterion tends to a maximum of two main parameters of interaction - loads and deformations at any construction solutions of the foundation. The article provides the results of argumentation of the adaptation criteria of the bases and foundations of any designs to environmental conditions during their design, construction and operation of the entire period.
    Key words: foundation, environment, systems interaction, parameters of ties, adaptation criterion, intersecting parameters, conformity fields, load, base settlement, deformation, deformation modulus.

    Abstract. A numerical methodology is proposed for investigations of the forced oscillations of shallow axisymmetric shells of revolution. We consider an axisymmetric shallow shell of revolution that performs small forced oscillations relative to an initial strain state caused by the static load and determined within the scope of the geometrically nonlinear deformation theory. To solve the problems of shell calculation with an arbitrary form of the generatrix, we use the Bubnov-Galerkin method in a mixed finite-element formulation. Unlike the common approach to solving such problems with the use of the finite element method in the deflection method form, the proposed approach has some advantages. One of them is the fact that obtained finite-element ratios have a simple structure. In this connection, the calculation of matrixes and vectors of the finite element does not require the use of numerical integration that positively influences on the accuracy of computations conducted. The analysis of the accuracy and convergence of the developed numerical algorithm is carried out. On the basis of the developed methodology, the effect of geometric nonlinearity on the process of shell oscillation is analyzed.
    Key words: finite element method in mixed formulation, Bubnov-Galerkin method, orthotropy, geometrical nonlinearity, shell, forced oscillations.

    Abstract. Results of the comparison of calculated data on the crack resistance of flexural reinforced concrete element at elevated process temperatures determined with the procedure set by the new regulatory document and on the basis of the non-linear deformation model with the use of the concrete state bilinear diagram are presented. Numerical studies were carried out for flexural reinforced concrete elements without preliminary stress of rectangular section. At this, the strength of concrete and reinforcement percentage were varied. As a result, it is established that the time point of crack formation, which was defined by the new regulatory document using the core moment procedure and on the basis of the simplified assumption diagram of the concrete state, yields somewhat underestimated results comparing with the previous norms. As a result of the numerical study, it is revealed that the understatement of crack resistance was caused by the underestimation of the elastic-plastic moment of sectional resistance in the new regulatory document, when calculating by the core moment procedure. When using the simplified bilinear concrete state diagram, decreased values of time point of normal crack formation are due to the low reduced deformation modulus for concrete. Results of the numerical study make it possible to work out recommendations on the adjustment of the calculation procedure for the crack formation time point with due regard for elevated process temperatures.
    Key words: calculation of flexural elements, ñrack resistance and deformability of flexural elements, nonlinear deformation model, core moments, diagram of deformation of concrete and reinforcement, elevated temperatures, bilinear diagram of concrete state.

    Abstract. The description of a nodal element of the metallic structural construction of the "BrSTU" system developed at the department of building constructions of the Brest State Technical University, which makes it possible to create structural constructions of any architectural form and expressiveness and cover the buildings with over 100 m spans with different basic geometry in plan, is presented. The nodal element of the "BrSTU" is made in the form of a hollow ball with holes in the wall. The ball is manufactured from two semi-spheres obtained by hot pressing from rolled metal which are connected by a butt joint with the partition of the edges. In the semi-spheres there are holes for fixing bolts, their diameter is 1.0 mm wider than the diameter of the corresponding fixing bolt. The analysis of stress-strain state of the hollow nodal junction of the "BrSTU" system under the many-axial loading with local loads is presented; the regularities of distribution of stresses and strains depending on the diameter and thickness of the hollow ball, sizes of reinforcing washers, values of local loads from the tension in the rods of the structure are established. The methods of determining the bearing capacity of the nodal element of the "BrSTU" system based on the comparison of maximum effort which acts on the unit, with maximum assumed effort stated on the basis of the strain diagram ("load-strain") at one-axis straining or compression of the hollow ball with holes and reinforcing washers is presented. The calculation formula for determining the bearing capacity of the node in the resilient area of steel work with prescribed geometrical dimensions of the hollow sphere, bolt diameters, sizes of reinforcing washers is obtained.

    Absract. Nowadays, in the practice of construction, thin-shells are mainly used as coatings for large-span buildings. Such constructions make it possible to considerably reduce the bending moment and the reinforcement consumption. The use of overlaps of multistory buildings on the basis of thin-shells gives the opportunity to significantly reduce the consumption of reinforcement, reduce the volume of concrete, and, consequently, decrease the overall load on the vertical load-bearing structures of the building. In this article there is an estimation of the economic effect of the use of floor slabs on the basis of thin-shells. The nature of the stress-strain state of the overlap with a small curvature of the lower surface and the distribution of the required reinforcement are considered. The assessment of the economic efficiency of different types of floor slabs differing from each other by the form of generatrix and the camber of arch is made. All the findings and results are described and justified. The design schemes are executed in the "LIRA SAPR" software package. As a result of the work conducted, the graphs of dependence of the consumption of concrete and reinforcement on the applied conditional payload and camber of arch have been obtained.
    Key words: overlap slabs, vaulted overlap, shells.

    Abstract. At present, the study of compositions of fine concretes with the use of waste of copper smelting production in Chelyabinsk Oblast is a relevant problem as the degree of pollution with these types of waste of regions of the Ural Federal District is very high. Results of the mathematical simulation of the strength of fine concrete with anthropogenic waste after 28 days of hardening under normal conditions at the low range of the true water-cement ratio are presented. The 4-factor mathematical model of concrete strength is developed; the regression equation of dependence of compression strength on the volume concentration of the neat cement, the true water-cement ratio, dosage of fine copper-smelting slag and a superplasticizer on the basis of polycarboxylates ethers is created. Statistical processing of the results of mathematical planning of the experiment is made, the adequacy of the constructed mathematical models is evaluated. Charts of contours of the pair influence of independent factors on the fine concrete strength at different levels of variation are constructed. Characteristics obtained confirm the feasibility to use this type of waste of non-ferrous metallurgy in concretes and also open the possibility of further study of fine concretes properties with increased true water-cement ratio.
    Key words: copper-smelting slag, fine concrete, anthropogenic waste, polycarboxylate superplasticizer, organic-mineral admixture, mathematical experiment planning.

    Abstract. At significant uneven sediments of buildings constructed on sand bases, there is a need for the alignment of the foundation or even lifting the building. To create the concrete massif for providing the support when lifting the building is possible by means of jet cementation. To achieve the required strength, the thickness of this massif can reach 20 m. To analyze the performance of this massif, the stress-strain state of the base was studied both due to its own weight and distributed load of the building (0.4 ÌÏà). Settlements of the massif were determined together with the sand base by means of increasing the load due to injection, increasing the specific weight of the material of the building base in the injection zone. The stress-strain state analysis of the base revealed the presence of limit state zones in the sand before injecting works when excavating the foundation pit.
    Key words: sand base, concrete massif, injection, settlements due to own weight of sand, energy model of soil.

    Abstract. The construction of the bridges is a special area of road construction with a number of features of construction and Assembly works which in turn complicates the organization of production and requires careful quality control of work performed. In the article the problems the number of which may be reduced in the construction process with proper control. The current situation makes it relevant to the idea of radical change of the existing system of organization of construction of bridge structures through the introduction of information modelling technologies. In the work proposed and justified the use of information modelling in the work of service building control through building information model of the object. Defined the leading role in the process of organizing the construction and function of service building control including interaction and exchange of data in the information model of the bridge structure. It is shown that the decision-making on elimination of discrepancies with the use of pairwise comparison matrix is the most rational and eliminates the influence of subjectivity do the work. On the basis of the practical use of the developed approach the analysis in comparison with the established process of interaction between participants in the construction and organization of construction production as well as the advantages of the first. It is revealed that this approach to construction will allow us to respond to the processes at the facility as well as to prevent the occurrence of dangerous situations and to reduce construction time.

    Abstract. The energy saving issue in the modern management systems with the distribution of thermal energy among consumers of different level is considered. The task of process optimization of heat supply of buildings and constructions in case of different types of connection of systems of heating, cooling and hot water-supply to thermal networks is set. A mathematical model based on the analysis and properties of the function of a material variable is offered for optimization of the distribution of thermal energy in the system of heat supply among the array of consumers. Basic provisions of the method, which received the name of "method of the threes", are based on the distribution of the located limit of resources for three, not necessary equal, parts taking into account the appropriate number of consumers of the considered resource in each of parts of the partitioned array. As a main optimality criterion, a local minimum of the target function which represents the amount of relations of three values of the resource limit to the appropriate number of its consumers in the received parts is selected. Necessary working formulas of the optimum allocation of resource limits in the array of consumers are developed.
    Key words: distribution of resources, mathematical model, local minimum of target function.

    Abstract. When increasing the density of urban areas, a priority value is providing the ecological safety. Main environmental harmful factors in the norms of urban planning are prohibitive, other factors and criteria of the urban environment are recommendatory, declaratory nature and do not imply qualitative grades. The lack of clear criteria for the quality of urban environment forces developers and consumers to determine its quality on a subjective level. Clear criteria for the environmental quality should be motivators for territorial authorities and operation bodies in its preserving. "Green" standards of construction should become the instruments for determining qualitative characteristics of the urban environment. Summer overheating of urban areas, a factor associated with the property of anthropogenic surfaces to reflect more intensively and to generate thermal energy than the surface of the natural landscape, have harmful (hazardous) thermal effects on humans. However this factor has not received a proper assessment in the standards of urban planning. The method of estimation of the environment safety of the local area according to the criterion of thermal effects on humans, the ability of green plantings to reduce it, and determination of the territory required for for placing of objects of gardening is presented in the article. Adjoining green spaces, which contribute to reduction in overheating of the territories, should be a continuous communication among the elements of the natural-ecological framework.
    Key words: ecological safety of urban environment, urban planning, "green" building standards, natural-ecological framework, objects of landscaping.
